Dynamic ecological system analysis

open access: yesHeliyon, 2019
This article develops a new mathematical method for holistic analysis of nonlinear dynamic compartmental systems in the context of ecology. The method is based on the novel dynamic system and subsystem partitioning methodologies through which ...

On the Dynamic Contact Angle in Capillary Flows [PDF]

open access: yesJournal of Chemical and Petroleum Engineering, 2021
The displacement of the contact line (CL) between two arbitrary immiscible flowing fluids was modeled. The present model is valid for a wide range of viscosity ratios of the phases. This is while the previously developed models reported in the literature

Robust Mode Analysis

open access: yesMathematics, 2021
In this paper, we introduce a model-free algorithm, robust mode analysis (RMA), to extract primary constituents in a fluid or reacting flow directly from high-frequency, high-resolution experimental data.

Analysis on the dynamic characteristics of debris flow in Jiangjia Ravine, China [PDF]

open access: yesE3S Web of Conferences, 2023
Dynamic characteristics determine the mobility of debris flow and are also key to hazard risk assessment. However, the dynamic process of natural debris flow is very complex.

DYNAMICS OF RELATIVISTIC FLOWS [PDF]

open access: yesInternational Journal of Modern Physics D, 2004
Dynamics of relativistic outflows along the rotation axis of a Kerr black hole is investigated using a simple model that takes into account the relativistic tidal force of the central source as well as the Lorentz force due to the large-scale electromagnetic field which is assumed to be present in the ambient medium.
